Quantum Spin Fluctuations as a Source of Long-Range Proximity Effects in Diffusive Ferromagnet-Superconductor Structures
A. Kadigrobov, R. I. Shekhter, M. Jonson
We show that quantum spin fluctuations in inhomogeneous ferromagnets drastically affect the Andreev reflection of electrons and holes at a ferromagnet-superconductor interface. As…
Dynamics of a three terminal mechanically flexible tunneling contact
A. Isacsson
The dynamics of a nanoelectromechanical system in the form of a three-terminal tunneling device is studied by analytical and numerical methods. The main results are the existence o…
Multi-filament structures in relativistic self-focusing
F. Cattani, A. Kim, D. Anderson +1
A simple model is derived to prove the multi-filament structure of relativistic self-focusing with ultra-intense lasers. Exact analytical solutions describing the transverse struct…
Coulomb blockade thermometry using a two-dimensional array of tunnel junctions
Tobias Bergsten, Tord Claeson, Per Delsing
We have measured current-voltage characteristics of two-dimensional arrays of small tunnel junctions at temperatures from 1.5 K to 4.2 K. This corresponds to thermal energies large…
A fast, primary Coulomb blockade thermometer
Tobias Bergsten, Tord Claeson, Per Delsing
We have measured the third derivative of the current-voltage characteristics, d^3I/dV^3, in a two-dimensional array of small tunnel junctions using a lock-in amplifier. We show tha…
Commutation relations for surface operators in six-dimensional (2, 0) theory
Mans Henningson
The A_{N - 1} (2, 0) superconformal theory has an observable associated with every two-cycle in six dimensions. We make a natural guess for the commutation relations of these opera…
Semiclassical trace formulae using coherent states
B. Mehlig, M. Wilkinson
We derive semiclassical trace formulae including Gutzwiller's trace formula using coherent states. This formulation has several advantages over the usual coordinate-space formulati…
Coherent transfer of Cooper pairs by a movable grain
L. Y. Gorelik, A. Isacsson, Y. M. Galperin +2
A coherent hybrid of states with different number of Cooper pairs can be built in a superconductor grain as a result of periodically repeated discrete encounters with bulk supercon…
The Non-Abelian Self Dual String on the Light Cone
Vanicson L. Campos, Gabriele Ferretti, Per Salomonson
We construct the scalar profile for the non-abelian self dual string connecting two M5-branes compactified on a light-like circle. The construction is based on a conjectured modifi…
Spin relaxation in asymmetrical heterostructures
N. S. Averkiev, L. E. Golub, M. Willander
Electron spin relaxation caused by the D'yakonov-Perel' mechanism is investigated theoretically in asymmetrical AB heterostructures. The total spin relaxation anisotropy is…
Microwave induced resonant backscattering in a one-dimensional mesoscopic channel
S. Blom, L. Y. Gorelik
We have studied a one-dimensional channel with a wider, straight region irradiated by an external electromagnetic field. In this system the interplay between interference effects a…
Collective versus single-particle effects in the optical spectra of finite electronic quantum systems
M. Santer, B. Mehlig
We study optical spectra of finite electronic quantum systems at frequencies smaller than the plasma frequency using a quasi-classical approach. This approach includes collective e…
Influence of the flow on the anchoring of nematic liquid crystals on a Langmuir-Blodgett monolayer studied by optical second-harmonic generation
Valentina S. U. Fazio, Lachezar Komitov, Christian Radüge +2
The influence of capillary flow on the alignment of the nematic liquid crystal MBBA on fatty acid Langmuir-Blodgett monolayers was studied by optical second-harmonic generation. Th…
Holographic Noncommutativity
David S. Berman, Vanicson L. Campos, Martin Cederwall +5
We examine noncommutative Yang-Mills and open string theories using magnetically and electrically deformed supergravity duals. The duals are near horizon regions of Dp-brane bound…
Phase diagram of an impurity in the spin-1/2 chain: two channel Kondo effect versus Curie law
Sebastian Eggert, David P. Gustafsson, Stefan Rommer
We consider a magnetic s=1/2 impurity in the antiferromagnetic spin chain as a function of two coupling parameters: the symmetric coupling of the impurity to two sites in the chain…
Comparative study of mixed monolayers of a calixarene with a fatty acid and a non-amphiphilic nematic liquid crystal
F. Nannelli, V. S. U. Fazio, Y. Matsuzawa +2
Many nematic liquid crystals (NLCs) lack a polar headgroup and thus are not able to form stable monolayers at the air/water (a/w) interface. A way to obtain monomolecular films of…
Electromagnetic energy penetration in the self-induced transparency regime of relativistic laser-plasma interactions
M. Tushentsov, F. Cattani, A. Kim +2
Two scenarios for the penetration of relativistically intense laser radiation into an overdense plasma, accessible by self-induced transparency, are presented. For supercritical de…

Stephan Endraß, Ulf Persson, Jan Stevens
In this paper we compute upper bounds for the number of ordinary triple points on a hypersurface in and give a complete classification for degree six (degree four or less is…
Josephson effects in a superconductor-normal metal mesoscopic structure with a dangling superconducting arm
R. Shaikhaidarov, A. F. Volkov, H. Takayanagi +2
We studied a mesoscopic cross-like normal metal structure connected to two superconducting (S) and two normal (N) reservoirs. We observed the Josephson effect under unusual conditi…
